How to cut metal stamping parts?1

In stamping processing, shearing is a frequently used process. For metal stamping plants, the reasonable choice of shearing equipment is very important. According to the customer's requirements and the different cutting equipment, the size and accuracy of the cut stamping parts are also different. Next, the precision author will introduce to you the different ways of cutting stamping parts. There are various cutting methods, including: 1. Hand shears and such as shears, 2. Shearing on vibration shears, 3. Shearing on discs, 4. Shearing on gantry shears, suitable for metal stamping with a thickness of less than 1 mm. For sheet metal, metal stamping parts cutting or semi-finished products processing, hand-cutting or cutting is used; the metal stamping part blanks suitable for 2mm thickness parallel lines or graphs are vibrating shears; the cutting blade is close to this and fixed. The lower shearing blade moves quickly and repeatedly, and the reciprocating frequency can be 1200-2000 times per minute; the shears are on the disc; the shears are all disc-shaped, and the left and right disc knives move at the same speed under the condition of shearing. Relative azimuth rotation. The sheared stamping die sheet material enters into the cutter head by the sliding friction between the upper body of the raw material and the cutter head for shearing. There are two types of shearing on the gantry shearing machine: flat blade shearing machine and oblique blade shearing machine. The left and right edges of the flat-blade shearing machine are parallel, and the sheet metal of the metal stamping parts is additionally cut on the total width in the working condition. The sheared blank has a better verticality, and its shearing force is relatively large. It is generally used for shearing thin sheets; for shearing on an oblique-blade shearing machine, the left and right blades cross in a certain angle of view. Compared with the flat-blade shearing machine, the shearing force is not strong, and it is more stable during work, but because the working pressure of the left and right shearing blades will cause the sheared blank to bend down and squeeze from the wound during the whole cutting process. Distortion is very serious when cutting thick and narrow strips. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
